Did you check out the power supply for proper operation since both the audio and video are gone? If PS is good then the problem may very well be on main board.

Your power supply is dead.
Power supplies can be purchased online for a couple hundred bucks, and replacement is fairly simple and requires only a screwdriver.
For those less tech-savvy, you may want to start saving for a new TV.

No sound and no picture


It may well be the power supply. Filter capacitors have a nasty tendency of blowing, as well as voltage control ICs. If the filter blows, you end up with a shaky DC signal that can't be effectively used by digital components (which make up about 80% of modern TV circuits). If you're within warranty/exchange then go for the manufacturer. If not, and you're comfortable with opening these things, then you can carefully (after unplugging and allowing it to discharge) take a glance inside. If any capacitor(s) are visibly blown out, then there's your problem.

Please check for bad electrolytic capacitors on both main board & power supply, if there is any "pup-up" one, replace it (them).
